Reliability, drivability, stealth and enhanced performance that cannot be bested are the highlights of APR's newest OEM-component based conversion package.

APR's engineers have expertly recalibrated the engine management system to allow for nearly flat torque delivery from 3000 RPM to 5000 RPM which results in a smooth linear pull throughout the power band. Keeping the track enthusiast in mind, this conversion package will not result in overpowering of the driveline but will allow for smooth acceleration to easily maintain control while cornering.

The Borg Warner K04 turbocharger selected by VAG engineers is perfectly sized for the 2.0 liters of displacement to allow for stout horsepower numbers as the RPMs increase with no dramatic fall off as redline approaches. This ensures plenty of power in the high RPMs for continued acceleration in the straights and positioning at the healthiest portion of the power band after corner exit.

APR provides all hardware and software needed to ensure a complete install. All items which can be pre-assembled on the turbocharger come pre-assembled by APR. The APR K04 turbocharger system consisting of the following:
